The player's denials of an issue with his then-former boss now appear honest after their reunion was sealed, with the highly-rated Caldara - who only officially linked up with the Bianconeri earlier this month after a switch from Atalanta - taking Bonucci's place at San Siro.

Bonucci made a shock switch to Milan a year ago, as the Rossoneri sought to bring in a raft of signings to once again emerge as the biggest Italian club. With Juventus scoring 86 goals and AC Milan having just 56 goals for in Serie A, the San Siro could use a top goal scorer.

As for Higuain, Milan now have a forward who has double-figure scoring tallies for the past decade, while scoring 20 or more goals in eight of those campaigns.

But he is now reportedly unsettled at Milan following the club's failure to finish in the Champions League places and wants to return to Juventus.
